Vudu has just been bumped to version 1.5

• If you only get halfway through a film before the 24-hour window is up, you can extend the rental period for a discounted price, $2 off HD movies and 1$ off regular ones.
  
• The option is available for a week after the flick expires, and then you have another 30 days to start watching, and 24-48 hours after you hit play.
  
• CONS- you can only extend a movie once.
